Unsolved Mysteries of Science: Time

Time feels simple—we experience it every second. Yet modern physics suggests it may be one of the deepest mysteries in the universe. Why does time appear to flow in one direction? Does the future already exist? Can time travel ever be possible? Is the present moment physically real, or merely a feature of human perception? From relativity and the arrow of time to closed timelike curves, quantum gravity, and the nature of causality, this series explores the most profound unanswered questions about time itself. The deeper you investigate time, the more reality begins to challenge common sense. ⏳🌌
